Description
Technical field
The utility model relates to a kind of steam flow measurement device, specifically a kind of isolation pressure obtaning device of steam flow measurement.
Background technology
In the steam flow measurement of traditional differential pressure type, the system of steam-flow meter forms more complicated, there is longer pressure guiding pipe, after a valve, drainer is installed, two drainers will be arranged in same level, and condensation liquid level has double altitudes and maintain a long-term stability (condensed fluid is generally water), and winter operation also needs pressure guiding pipe, condenser system to be incubated, to accompany heat, the careless slightly fault that just causes, the maintenance workload of instrument is larger.Although some integrated throttling gears are made of one throttling element and differential pressure transmitter, shortened impulse pipeline, improved condenser system, but also solve condensed fluid, be not sometimes back to and in jet chimney, cause the difficult problems such as liquid level is inconsistent, and integrated apparatus versatility has been poor.In a word, in prior art, also cannot effectively process an easily difficult problem for freezing contour maintenance of the Winter protection of steam flow measurement, condensed fluid in service loss, drainer.
Summary of the invention
For above-mentioned deficiency, the utility model provides a kind of isolation pressure obtaning device of steam flow measurement, efficiently solves the defects such as Winter protection, the maintenance workload of traditional steam flow measurement device is large, has realized the operation steady in a long-term of steam flow measurement device.
The technical scheme in the invention for solving the technical problem is: a kind of steam flow measurement device, comprise throttling element and differential pressure transmitter, described differential pressure transmitter is by just symmetrically arranged, negative pressure taking pressure pipe road is connected on the throttling element being arranged in jet chimney, just described, negative pressure taking pressure pipe road comprises pressure guiding pipe and condensation spacer assembly, it is characterized in that: described condensation spacer assembly comprises the U-shaped pipe that injects silicone oil, one end of described U-shaped pipe is connected on throttling element by pressure guiding pipe, the other end is connected to differential pressure transmitter by pressure guiding pipe, the pressure guiding pipe at described connection U-shaped pipe two ends is horizontally disposed with, pressure guiding pipe between described U-shaped pipe and throttling element is provided with valve one time.
Further, one end of described U-shaped pipe is provided with pouring orifice near port, and described pouring orifice is provided with gland bonnet.
Preferably, described U-shaped pipe and pressure guiding pipe are weldless steel tube, and U-shaped pipe and pressure guiding pipe seamless link.
Preferably, the U-shaped pipe on described positive and negative pressure pressure pipeline and pressure guiding pipe are one and bend the weldless steel tube forming.
Good effect of the present utility model is: the utility model is just, negative pressure taking pressure pipe arranges U-shaped pipe in road, this U-shaped pipe and pressure guiding pipe can be adopted as a weldless steel tube and bend and form, by inject silicone oil in U-shaped pipe, reach the condensation isolation object to steam, the pressure pipeline that efficiently solves traditional steam flow measurement device is long, need to install cooling tank, need insulation companion heat, condensed fluid easily runs off, transmitter takes normal debugging, pipeline and transmitter are easily freezing, the defects such as maintenance workload is large, realized the long-term stability operation of steam flow measurement facility, reduced workload, reduced labour intensity, saved tracing thermal-insulating cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of U-shaped pipe described in the utility model;
In figure, 1 jet chimney, 2 throttling elements, 3 pressure guiding pipes, No. 4 valves, 5 U-shaped pipes, 51 pouring orifices, 52 silicone oil, 53 gland bonnets, 6 differential pressure transmitters.
Embodiment
As depicted in figs. 1 and 2, the isolation pressure obtaning device of a kind of steam flow measurement of the present utility model, comprise throttling element 2 and differential pressure transmitter 6, described differential pressure transmitter 6 is connected on the throttling element 2 being arranged in jet chimney 1 by symmetrically arranged positive and negative pressure pressure pipeline, and described positive and negative pressure pressure pipeline comprises pressure guiding pipe 3 and condensation spacer assembly; Described condensation spacer assembly comprises the U-shaped pipe 5 that injects silicone oil, and one end of described U-shaped pipe 5 is connected on throttling element 2 by pressure guiding pipe 3, and the other end is connected to differential pressure transmitter 6 by pressure guiding pipe 3, and the pressure guiding pipe at described connection U-shaped pipe two ends is horizontally disposed with; U-shaped pipe 5 on described positive and negative pressure pressure pipeline and pressure guiding pipe 3 bend and form by a weldless steel tube, pressure guiding pipe between described U-shaped pipe 5 and throttling element 2 is provided with valve 4 one time, one end of U-shaped pipe 5 is provided with pouring orifice 51 near port, to inject silicone oil 52 in U-shaped pipe, described pouring orifice is provided with gland bonnet 53.
The pressure guiding pipe of U-shaped pipe described in the utility model both sides need to keep level, and it is symmetrical that positive and negative pressure pipeline keeps, and pressure pipeline is short as far as possible, during installation after a valve closing, from pouring orifice, in U-shaped pipe, inject silicone oil, while normally working, silicone oil plays buffer action, prevents that steam from damaging transmitter.Silicone oil is made condensation spacer pad and is had a clear superiority in compared with water, it is colourless, tasteless, nontoxic, not volatile, there is excellent resistant of high or low temperature, can at-50 ℃～+ 200 ℃, use for a long time, when steam is normally carried, the radiations heat energy of jet chimney is enough to guarantee the normal work of differential pressure transmitter and pressure pipeline, anhydrous in pressure pipeline while stopping vapour, winter can freezing pressure pipeline and differential pressure transmitter yet, has solved the pipeline instrument insulation problem of headache.
Tradition drainer steam flow measurement device generally uses water as condensed fluid, the liquid level of two drainers will have double altitudes and will maintain a long-term stability, and water is volatile, when steam is carried, it is hot being subject to high-temperature steam to affect drainer, and the water in it will produce volatilization, and the time has been grown, the liquid level of two drainers will be inconsistent, thereby produce error in dipping.And the utility model adopts silicone oil to make spacer pad, not volatile, and also because the pressure pipeline of U-bend both sides is levels, silicone oil can not flow in jet chimney, and the amount of long-play silicone oil can not change like this, is conducive to keep measuring accuracy.
Tradition drainer steam flow measurement device is because drainer outlet is in drainer bottom, if differential pressure transmitter is below drainer, maintainer, when the blowdown of differential pressure transmitter end, is easy to just the water in drainer be drained, so just need water filling again, adjust liquid level equilibrium; And the utility model is noted silicone oil in U-shaped pipe, as long as close valve one time, how blowdown can not cause silicone oil to run off.
The above is preferred implementation of the present utility model; for those skilled in the art; not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, these improvements and modifications are also regarded as protection domain of the present utility model.
